(Cl. 221-9S) 1 Claim.

This invention relates to attachments for containers of liquids or othermaterials that can be poured, and is adapted to regulate the delivery ofsaid materials from said containers.

An object of the invention is to provide a device of this kind Which canbe readily secured to the mouth of the container, and which is soconstructed that it Will measure out and issue a predetermined quantityWhenever the container is actuated to assume discharge position.

Another object is to provide such an attachment comprising few parts andcapable of being easily manufactured at 10W cost.

The advantages of the invention are set forth in the followingdescription, and the novel features are recited in the appended claims;but the disclosure is explanatory only and Various changes in shape,size and other details may of course be adopted in practice.

On the drawing:

The single gure is a longitudinal section of an attachment according tomy invention.

My improvement embraces a shell or casing I, the interior of Which isdivided into tWo chambers 2 and 3 by a transverse partition d. The shellhas a neck 5 which has a covering of some compressible substance, suchas cork 6, to be inserted tightly into the mouth of the container, suchas a jug or bottle.

The neck 5 extends through the chamber 3 and communicates With thechamber 2. Its inner end is controlled by a valve l, the movement ofwhich is limited by a cage 8. The chamber 3 has a spout 9, securedaround an opening in the partition 4. This partition does not extendentirely across the inside of the shell i, but has a downturned edge IWhich leaves an opening I I between the chambers. An air tube I2,opening through the wall of the chamber 2 on the side opposite thespout, and extending through the recess II', projects into the chamber3.

In use, the container is tilted to the left and the contents run pastthe valve 'I into the chamber 2; some of the air in the shell escapingthrough the tube I2. As soon as the level of the liquid rises in thechamber enough to cover the inner end of tube 5, no more liquid canenter this chamber. When the container is righted, the valve 'I closesand liquid in the chamber 2 runs down into the chamber 3 through theopening I I. By the tilting of the container again, the person holdingit causes the liquid in the chamber 3 to issue from the shell I by Wayof the spout 9, which extends to the exterior of the shell; air nowentering by the tube I2. At the same time the upper chamber 2 is relled.

The operation is thus repeated as often as the container is manipulated.This attachment thus served to deliver the liquid in measured quantitiesonly; corresponding to the size of the device.

Having described my invention, What I believe to be newl and desire tosecure and protect by Letters Patent of the United States is:

An attachment for a container comprising a shell With a partition insidedividing the interior into a pair of chambers, a neck projecting fromthe shell to be secured to the mouth of the container, said neck havingan extension running through the partition and communicating with one ofsaid chambers, said partition having an opening at one side to connectsaid chambers, a spout in the chamber with which said extensioncommunicates and affixed to the partition at the side opposite saidopening, said spout communieating with the other chamber and extendingto the `outside of said shell, a non-return valve in the neck extensionadjacent the partition, and an air tube attached to the Wall of thechamber With which said extension communicates and extending into theother chamber and open to the atmosphere through said shell.
